well I just tried it out... I approved 17 posts and didn't get an assertion error! 
though it took quite a while before the webpage was finnished loading (about 2
minutes) but the process load on the machine didn't get any higher than 2.5

I wonder though what happens if some impatient moderator decides not to
wait before the page finnishes loading, switches to a differen webpage  and therefor 
breaks the python cgi process... will some approved posts stay in the queue instead?

I mentioned before that I think that it could be better if the cgi scripts
don't do anything more than just "mark" message as being approved... cgi scripts
should have a short life time and definately shouldn't be waiting for something too long...

btw i used the original LockFile.py this time...
